Abstract: Techniques for connectivity using a geographic phone number are described. According to various implementations, techniques described herein enable various policies pertaining to the use of telephone numbers at different locations to be enforced. For instance, techniques described herein enable a client device that is outside of a permitted geographic area for a geographic phone number to use a non-geographic phone number to connect a call, while the call can be routed using the geographic phone number.

Abstract: Techniques for emergency calling are described. In one or more implementations, data corresponding to an emergency call is received over a network from a communication client implemented al a client device. A registered location of the communication client and an updated location of the client device is obtained, and the updated location of the client device is compared to the registered location of the communication client. If the updated location is different than the registered location, the data of the emergency call is routed along with the updated location to a public-safety answering point.

Abstract: A method for facilitating communication between a mobile object and a remote system may include obtaining channel information indicating which wireless channels are available in a plurality of locations along a route to be traveled by the mobile object. The channel information may be used to select one or more available wireless channels for communicating with at least one relay station while the mobile object travels along the route. One or more messages may be sent to the remote system via the at least one relay station. Wireless communication between the mobile object and the at least one relay station may occur via the one or more available wireless channels.

Abstract: Techniques for enhanced error protection for high priority communication sessions are described. Generally, the described techniques enhance error protection for high priority communication sessions, such as emergency calling, such that the high priority communication sessions are essentially error free. According to various implementations, user input to initiate a communication session over a network is received at a communication application. In response to detecting that the communication session corresponds to a high priority communication session, error protection for data of the high priority communication session is enhanced. The data may be enhanced in a variety of different ways, such as by performing forward error correction on the data. The enhanced data of the high priority communication session is then communicated over the network to an endpoint.

Abstract: A system for controlling access to priority access wireless resources divides a radio spectrum into first wireless resources for use by general access devices and second wireless resources for use by priority access devices. A base station receives, from a server, information concerning the first and second wireless resources, including resource entries corresponding to each of the first and second wireless resources. Upon receiving a request for available wireless resources from a general access device, the base station provides one of the resource entries corresponding to the second wireless resources. The system includes a general access device which aggregates resource entries for the first and second resources for communication with another general access device. When the general access device detects priority access to the second resource, the general access device either releases the second resource or reduces transmission power on the aggregated first and second resources.

Abstract: A method for facilitating efficient reading of radio frequency identification (RFID) tags may include encoding a sequence of information bits using an error-correcting code to generate encoded information. The sequence of information bits may be associated with an object. The encoded information may be distributed among a plurality of RFID tags such that recovering the sequence of information bits does not require all of the plurality of RFID tags to be read correctly. The plurality of RFID tags may be attached to the object.

Abstract: A method for authenticating a password may include receiving a first entered password and determining a difference value between the first entered password and a stored password. The difference value may result from comparing the first entered password to the stored password. The method may also include determining that the difference value does not meet an acceptability standard, denying access to a restricted element, and determining a new acceptability standard.

Abstract: A device for operating a service network includes a processor and a memory in communication with the processor. The memory includes executable instructions that, when executed by the processor, cause the processor to control the device to perform functions of determining that a communication session is initiated between a first device connected to a first network and a second device connected to a second network, the service network connected between the first and second networks; identifying an attribute of the communication session; determining, based on the identified attribute, whether the communication is authenticated; and when it is determined that the communication is authenticated, sending, to the first or second network, a session notification indicating that the communication session is authenticated with the service network, which allows the first network to route a data stream for the communication session as a trusted data stream.

Abstract: A method for mobile device communication includes, on a mobile computing device, receiving a request to establish a communication with a specified remote device. One or more unique hardware addresses of one or more network devices in a local environment of the mobile computing device are detected.
